• Combined current resource of 52 mill tonnes
and total in-situ Cu eqv. of 693.000 tonnes at
Nussir and Ulveryggen.
• Strong potential in the mid and west section
of Nussir to be proven during 2014.

Fortsatt sterk satsning på prospektering
• Government Program 2011-14
• 100 mill NOK to be spent over 4 years
• Repparfjord window received the highest
priority, due to its importance as a host area
for Nussir as a first mover.
• Helicopter borne geophysics
• Seismic studies
• Structural geology, PhD thesis
• Sequence dating
• Ground surveys
• Nussir ASA Program 2011-14

Flowsheet and Process design
• SGS Lakefield and
Woodgrove Technologies
(Canada) have finalised
process design, flowsheet,
and choice of process
equipment during 2010-11.
• Straight forward grinding and
flotation process.
• High recovery
• High grade
• Very low level of unwanted
elements in concentrate
• Low level of flotation
chemicals consumption
• Highly automated plant
Plant layout
• Layout designed to fit within
the existing plant building.
• Semi autogenous grinding
lowering process Opex
• Potential of lowering plant
Capex with sourcing of used
equipment
• Highly efficient new flotation
technology (SFR) needs
50% less floor space.
• State of the art press filter
technology for dewatering
